ABSTRACT:
A storage apparatus includes memory devices each having a storage element with a characteristic that the application of an electric signal not lower than a first threshold signal allows the storage element to shift from a high resistance value state to a low resistance value state, and that the application of an electric signal not lower than a second threshold signal, which has a polarity different from that of the first threshold signal, allows the storage element to shift form a low resistance value state to a high resistance value state, and a circuit element connected to the storage element in series to be a load; wherein the memory devices are arranged in a matrix and one terminal of each of the memory devices is connected to a common line; and wherein an intermediate potential between a power supply potential and a ground potential is applied to the common line.
